Jeep CJ-7 Spare Tire Sizes
The Jeep CJ-7 has used a 5x5.5" bolt pattern for all models from 1976 to 1986 along with tire diameters ranging from 27.1" to 28.9" tall. Using a temporary spare tire with a diameter close to the standard tire has many benefits, especially for modern vehicle applications. Tire diameter as well as wheel diameter clearance have been taken into account for the specific Jeep CJ-7 years and options. In this case, using a non-temporary Full-Size tire as your spare, is the recommendation for all applications.
